Title: Manufacture of glass
IPC: C03B18/00
Filed: 1974-11-22
Abstract: Surface modified glass is produced by method and apparatus in which the glass is contacted with a molten body, for example of a molten metal or molten alloy while the glass temperature is such that it can be modified by migration of cations from the molten body into the glass surface. This cationic migration is electrically induced and the molten material is periodically connected as a cathode with respect to the glass for a preset time sufficient at least partially to deoxidise the molten material. Non-oxidising conditions may be maintained in the molten material and the electrical action at the interface between the molten body and the glass while the molten body is connected as a cathode causes reduction of at least a proportion of the cations in the glass surface to produce a metallic dispersion.

Title: Process for the preparation of melamine
IPC: C07D251/60
Filed: 1978-01-18
Abstract: An improved process for the preparation of melamine from a feed of urea, thermal decomposition products of urea, or a mixture thereof, in the presence of a catalyst and an ammonia-containing gas.

Patent ES-476415-A1 (ES)
Title: Fuel system for internal combustion engine
IPC: F02D17/02
Filed: 1978-12-28
Abstract: The disclosure illustrates a fuel control valve for a fuel system of a compression ignition engine which utilizes unit fuel injectors operating on the principle that the fuel pressure applied to the injectors determines the quantity of fuel injected into the engine cylinders. The fuel control valve is connected in the supply line for half of the injectors of the engine. The valve has a plunger which blocks off flow to these injectors whenever the fuel system pressure is below a predetermined level. When the pressure exceeds that level, the plunger displaces to a position where it permits flow to the injectors and offers a minimum restriction to flow. The pressure level is set at a level which reflects engine operation above idle but below normal engine operating conditions. The net effect is to substantially reduce the generation of white smoke during engine startup and while idling for extended periods of time while not affecting normal engine operating conditions. The selective termination of fuel to a portion of the cylinders has a beneficial effect on other engine emissions.
